LM2500?

LM2500? / LM2500+? / LM2500+G4?

The LM2500? is a GE industrial gas turbine which derives from the CF6-6 aircraft engine. It has been maintained and repaired by MTU since 1981. Unlike the LM6000? gas turbine, the LM2500? is designed with a single-rotor gas turbine and an aero-dynamically coupled power turbine. The LM2500? consists of a sixteen-stage compressor, a fully annular combustor, a two-stage high-pressure turbine and a high-efficiency power turbine. The LM2500? gas turbine is the most popular aero-derivative in the 20 to 25 MW class.

The LM2500+? and the LM2500+G4? are uprated versions of the basic LM2500? and offer 30.5 MW and 36.3 MW of power.
